Summary
Seeweb
hosting transit isp
1,055 BGP neighbours, the most of any network in this sweep, and five separate full-size IPv6 allocations.
What it's used for
- Web hosting, colocation and cloud services. 81,408 addresses in 35 IPv4 prefixes, 10 IPv6 prefixes, and 1,055 observed BGP neighbours.
Notable
- Netnames run from
IT-SEEWEB-19980908andIT-SEEWEB-19990412through 2000, 2001, 2005, 2009, 2010, 2011 andIT-SEEWEB-20120712. - One block breaks the pattern:
176.56.128.0/21, netnameEE-128BIT-20110530, an Estonian registration. - The IPv6 side holds five
/29s —2001:4b78::,2a04:2700::,2a05:be80::,2a0b:fd40::and2a0d:b000::— plus a/31and four/32s. - One sampled address of eighteen answered, as
pop3.f2.net.
Interesting
- Over a thousand neighbours puts this network among the most connected in the number range, and it gets there on 81,000 addresses. Hosting companies peer with everyone they can, because every network they reach directly is traffic that costs them nothing and arrives faster.
- Five separate
/29s is five full registry allocations. Nobody is granted that many by asking; they arrive attached to companies that were bought, each bringing its own membership and its own space. The IPv6 inventory is a list of acquisitions in a way the IPv4 inventory is not. - An Estonian netname inside an Italian hosting inventory is the address market at work, and
pop3.f2.netnames a mail protocol on a brand that appears nowhere else in the record.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 453 networks and 1,853 prefixes, as published 2026-11-05. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
